Duplicate Flights/Codesharing

Mon May 08, 2006 8:06 am

Hi there,

visiting the airport quite often I always wonder about the duplicated flights on airport information displays. E.g. in WAW we have lots of flights that are codeshared between LO, LH, UA and even NH (as well as other Star Alliance members), resulting in flights duplicated 2 or 3 times on the displays (with different flight numbers), further resulting in displays' decreased informativity (duplicated flights - more rows occupies - less flights visible).

Is there any effort taking place to unify this mess, e.g. within a particular alliance at least? I would love to see it like "SA0024(LO)" (read: Star Alliance flight#0024, operated by LOT) instead of "LO1234/LH5678/UA9012" and so on...

I know in other airports problem is solved so displays are not cluttered with almost-duplicate entries, but still, having an unified system would make many lives easier.

Is there anything happening in the area? Any other ideas?

The FIDS system that I am familiar with uses only one line, but it switches between each code share flight, while maintaining the original flight number.

DTW has a similar system.

My guess is that codeshares are not part of the alliances. That is, while carried out by airlines within the alliance, they are the result of specific agreements between airlines. So you can't just call it a Star Alliance flight or whatever.

Also as Xjramper points out, newer displays switch between numbers so that only one line is used.

OK, that would make sense leaving it the way it is. But perhaps unifying at least the flight number (the numeric part, apart from airline code) would be convenient? E.g. flight# 5000 and above would be reserved for shared flight numbers (just an example).

That is one of optimal approaches.

I have heard of a good solution deployed in CPH (I've been there but didn't notice), where they have two flight# fields for each flight entry, first one showing the main flight number (i.e. the flight number of the actual operator, e.g. SK---) and the second one cycling through codeshared flight numbers (e.g. UA----, LO----, LH----, etc).

that wont work, you still need a unique flight number per airline.

Normally airlines reserve ranges for codeshares. But not if it's their own equipment, and thus not a codeshare for them. Since practically all airlines have their own systems, unification is probably more trouble than it's worth.

That makes a lot of sense to me - I hate it when I'm looking on a board for CO46 to EWR and have to wait through KL8743 to EWR, NW9245 to EWR, EK8832 to EWR, etc. to make sure it's the right flight.
